I've had a lot of luck with the following list:
ISD2
Motti
ECM
ISD 2
ECM
XI-7 turbolasers
Wing Commander
Avenger
Firespray
Firespray
Firespray
Mauler Mithel
Rhymer
Dengar
I like these upgrades, and they've done really well for me. But my question is, should the XI-7 be on the avenger, or on Motti to make him dangerous as well?
The idea of course is to use wing commander to send the bombers in, and the enemy either spends their defense tokens and has them unavailable for when avenger shoots, or they let the bombers put their damage wherever they like and avenger has a free ride anyway. But perhaps Motti should be the one using the wing commander and XI-7 to dish damage before his shots that can't be ignored, forcing them to use tokens, and then the mostly naked avenger capitalizes on it?
